Search "cake shop near me" from almost anywhere between Parramatta and Riverstone and you'll get dozens of results — but not all of them make eggless cakes, and even fewer make every cake eggless as standard. Num Num's Bakery runs two shops, Harris Park and Riverstone, and between them we've published a dedicated local guide for suburbs stretching from the Parramatta CBD to the Hawkesbury fringe. This page is the map: every catchment, every cluster of suburbs, and a link straight to your area's guide.
We split coverage into two catchments because that's genuinely how the two shops work — not as a marketing device, but because it reflects which kitchen is realistically closest for each part of Sydney. Below, you'll find the Harris Park catchment (Parramatta and Cumberland), the Riverstone catchment (Blacktown and the north-west), and a short explanation of how ordering and collection work across both.
- Num Num's Bakery's blog maps 80 Sydney suburbs across two catchments.
- Harris Park covers 45 suburbs; Riverstone covers 35, across Greater Sydney.
- Both shops serve all of Greater Sydney, not just suburbs listed here.
- Standard cakes need 48 hours; custom or festival cakes need 4–5 days.

How Many Sydney Suburbs Does Num Num's Bakery Actually Cover?
Num Num's Bakery publishes a dedicated suburb guide for 80 individual Sydney suburbs today, according to our internal site count taken in July 2026 — 45 in the Harris Park catchment and 35 in the Riverstone catchment. That figure isn't the limit of where we serve; both shops take orders from anywhere in Greater Sydney. It's simply how many areas already have a local guide covering flavours, ordering steps, and the realistic collection window.
Of our 80 published suburb guides, 45 sit in the Harris Park catchment and 35 in the Riverstone catchment. That's a rough 56/44 split. It roughly mirrors how our order volume has actually divided across the two shops since Riverstone opened (Num Num's Bakery internal site and order data, July 2026).
This list keeps growing. New suburb guides get added most months, as we notice repeat orders coming from an area that doesn't have one yet. If your suburb is missing today, it may simply not have reached the front of that queue.
Why Split Sydney Into Two Catchments Instead of One Citywide Zone?
The two catchments exist because the population and geography genuinely split that way, not because of an arbitrary line on a map. As of the 2023 Estimated Resident Population, City of Parramatta had 269,145 residents. Cumberland Council had a further 245,323. That's a combined 514,468 people within the Harris Park catchment's core council areas alone, before counting the Ryde and inner-west fringe suburbs we also guide from Harris Park.
The Riverstone catchment centres on Blacktown City, which reached 426,202 residents by June 2023 and is growing at 3.71% annually. In the 2023–24 financial year, ABS Regional Population data recorded Box Hill–Nelson growing by 18,386 people (27%) and Marsden Park–Shanes Park by around 20% — both suburbs sit inside our Riverstone catchment, and both are among the fastest-growing statistical areas in the entire country.
In the 2023–24 financial year, Box Hill–Nelson grew by 18,386 people (27%), one of the fastest growth rates recorded anywhere in Australia (ABS, Regional Population 2023–24). For a bakery, that kind of growth means more new residents each year who haven't yet found their nearest eggless cake shop — which is exactly why a suburb-by-suburb guide matters more here than in a slower-growing area.
Which Suburbs Fall Inside the Harris Park / Parramatta Catchment?
The Harris Park catchment runs from the Parramatta CBD out through Cumberland and up to the Ryde fringe. Every suburb below is a genuine drive of well under half an hour from our Harris Park kitchen. We group it into four clusters below, because "45 suburbs" as a flat list tells you nothing about the area. Grouped by the roads and communities that actually connect them, it does.
Parramatta Core.
This is the shop's home turf, all within a 10-minute radius: Parramatta, Harris Park, Rosehill, Camellia, Granville, Clyde and Rydalmere. Most of our walk-in and short-notice pickups come from this cluster.
Cumberland Belt.
This cluster sits south and west of Parramatta, in the Cumberland Council area. It connects mainly via Woodville Road and the Hume Highway, and covers Auburn, Lidcombe, Berala, Regents Park, Merrylands, Holroyd, Guildford, Guildford West, South Granville, Woodville, Yennora and Chester Hill. This is one of Sydney's most multicultural corridors. A significant share of our Diwali, Eid and wedding-season orders come from here.
Westmead–Toongabbie Corridor.
This is the biggest single cluster, running north and west along the Great Western Highway and Old Windsor Road. It's also the one that borders the Riverstone catchment most closely. It covers Westmead, Northmead, North Parramatta, Constitution Hill, Winston Hills, Toongabbie, Old Toongabbie, Wentworthville, Greystanes, Girraween, Pemulwuy, Pendle Hill, Mays Hill, Oatlands, Dundas Valley and Telopea.
Ryde–Inner West Fringe.
Further east, still comfortably closer to Harris Park than Riverstone: Eastwood, Epping, Carlingford, North Rocks, Homebush, Strathfield, Ermington, Melrose Park, Newington and Silverwater. See our broader western Sydney cake shop guide for more on this wider area.
Which Suburbs Fall Inside the Riverstone / North-West Catchment?
The Riverstone catchment covers Sydney's fastest-growing corridor, running from Blacktown City through the Hills District to the Hawkesbury fringe. From our Riverstone shop, every suburb below is within a realistic same-morning collection window. As above, we've grouped it into four clusters rather than one long list.
Riverstone–Schofields Growth Corridor.
The newest housing estates in Sydney, built around the Sydney Metro Northwest line: Riverstone, Schofields, The Ponds, Marsden Park, Vineyard, Grantham Farm, Colebee and Box Hill. Several of these suburbs didn't exist as distinct postcodes a decade ago.
Rouse Hill–Kellyville–Hills District.
This is a more established, family-dense part of the Hills Shire, reached east along Windsor Road and Old Northern Road. It covers Rouse Hill, Tallawong, Kellyville, Kellyville Ridge, Beaumont Hills, Bella Vista, Castle Hill, Baulkham Hills and Glenhaven.
Blacktown–Quakers Hill Belt.
This is the most populous cluster in the catchment, running south along Sunnyholt Road and Richmond Road. It covers Quakers Hill, Blacktown, Seven Hills, Rooty Hill, Prospect, Kings Park, Plumpton, Marayong, Dean Park and Acacia Gardens.
Outer North-West / Hawkesbury Fringe.
The furthest reaches of the catchment, still a manageable drive for a planned pickup: Stanhope Gardens, Parklea, Glenwood, Kings Langley, Dural, Annangrove, Richmond and Windsor. For a wider view of this whole region, see our north-west Sydney eggless cakes guide.
From taking orders across both catchments, we've noticed a pattern. The Riverstone side skews more towards weekend collection for kids' birthday parties. Harris Park sees a steadier flow of weekday pickups tied to office celebrations and cultural events near Parramatta CBD. Neither pattern is fixed — it's just what our order data has shown since Riverstone opened.
How Does Collection and Delivery Actually Work Across These Areas?
Every one of the 80 suburbs above follows the same ordering process, regardless of catchment: message us on WhatsApp, confirm your flavour and pickup time, then collect from whichever shop is closest. Num Num's is primarily click-and-collect, which keeps a fragile, fresh-cream cake intact far better than a courier box does. We've written a full breakdown of courier delivery versus click-and-collect, and how to transport a cake safely in your own car, in our dedicated cake delivery in Sydney guide. This page focuses on where we cover, not how the handoff itself works.
- Find your catchment: use the suburb lists above to confirm whether Harris Park or Riverstone is genuinely closer to you.
- Browse flavours: check the Our Cakes page for the full 15-flavour range — every single one is 100% eggless.
- Message your order: send your date, design brief and preferred shop to +61 425 697 725 on WhatsApp.
- Collect fresh: pick up at your confirmed time from Harris Park or Riverstone — both have easy on-site or street parking.
You can also check your own route on Google Maps before you order, since traffic on the M4 and Windsor Road corridors varies a lot by time of day. Once you know which shop suits your suburb, the Order Online page has full sizing guidance for parties of any size.
How Far in Advance Should Each Catchment Order?
Lead time depends on the cake, not the catchment — a standard cake needs at least 48 hours' notice from either Harris Park or Riverstone, based on our internal order data across both shops in 2025–26. Custom, tiered or heavily decorated cakes, and anything ordered during Diwali, Eid, Christmas or NSW school holidays, need 4–5 days regardless of which suburb you're collecting from.
The one real difference between catchments is when demand peaks. Riverstone's newer growth suburbs — Marsden Park, The Ponds, Box Hill — tend to spike around weekend birthday parties. Harris Park's Cumberland and Parramatta suburbs see a steadier midweek flow tied to cultural events and office celebrations instead. Neither pattern changes the minimum notice required.
Message us your flavour, date and preferred shop. 48 hours is all we need for most orders, and we'll confirm everything in writing before you collect.
What If My Suburb Isn't Listed Here?
Both shops serve all of Greater Sydney, so a missing suburb guide never means we can't help — it just means that area hasn't had a dedicated page written yet. From our order history, we regularly fulfil orders from suburbs adjacent to the 80 listed above, including parts of the wider Hills District, the Hawkesbury and the Cumberland fringe that don't yet have their own guide.
The suburbs most likely to get a dedicated guide next are the ones bordering existing clusters — think Kellyville Ridge's neighbours or Guildford's immediate surrounds. That's usually where genuine repeat demand shows up first in our order data, rather than suburbs picked at random off a map.
If you don't see your suburb above, message +61 425 697 725 with your postcode. We'll tell you honestly which shop is closer and what collection window is realistic — no guesswork required.
Frequently Asked Questions
How many Sydney suburbs does Num Num's Bakery cover?

What's the difference between the Harris Park and Riverstone catchments?
The Harris Park catchment covers Parramatta, Cumberland and the inner western corridor; the Riverstone catchment covers Blacktown, the Hills District and the north-west growth corridor. Both areas use the same 100% eggless menu and the same 48-hour ordering process — the split simply reflects which shop is genuinely closest for each suburb.
My suburb isn't on this list — can I still order?
Yes. Both Harris Park and Riverstone serve all of Greater Sydney, not only the suburbs listed here. If your suburb doesn't have a dedicated guide yet, message +61 425 697 725 with your postcode and we'll confirm the nearest shop and realistic collection timing for your area.
How far in advance should I order, and does it depend on my catchment?
No — lead time depends on the cake, not the catchment. Standard cakes need at least 48 hours' notice from either shop. Custom, tiered or festival-period cakes such as Diwali, Eid, Christmas or school holidays need 4–5 days, based on our internal order data across both catchments in 2025–26.
