The total budget
| Category | Spend | What you get |
|---|---|---|
| Decor hire (HnK Cake Smash Hero set) | $378 | Backdrop, marquee 1, plinth, garland, welcome sign |
| Cake | $120 | Single-tier custom decorated + smash cake |
| Food | $200 | Grazing board + 2 platters |
| Tableware + linens | $45 | Disposable, themed |
| Photos (phone tripod + free editor) | $25 | Self-shot + Adobe Lightroom mobile |
| Outfit + cake smash outfit | $60 | Kmart or Cotton On Baby |
| Total | $828 |
That's $828 against a Sydney 1st birthday average of $1,200–$1,800 with similar decor. The savings come from hosting at home (no venue hire), buying tableware over hiring it, and not hiring a photographer.
Six weeks out
Lock the date
Saturday afternoons book up fastest with cake makers and decor hire. Pick a date with the lawn looking good (avoid late summer scorch — March or autumn weeks are kinder).
Think about weather backup: do you have a covered patio or large shade sail? If not, build in a backup plan (canopy hire is $100–$200 from Bunnings or local pop-up tents).
Decide guest list size
Aim for under 30 adults + kids. Past 30 your backyard becomes uncomfortable, kitchen overflows, and you'll spend the whole day refilling drinks instead of being present.
Book decor hire
Browse our catalogue or jump straight to a bundle like the Cake Smash Hero set ($378). Bundles include delivery + setup — meaning you're not stressed at 8am inflating balloons.
Book the cake
Sydney home bakers usually need 3–4 weeks. For a single-tier 6" custom-decorated cake plus a small smash cake, budget $100–$150. Recommendations from Western Sydney: Sweet Baby Cakes, The Frosting Project, Cookie Crumbs — or check Instagram for #sydneycakemaker.
Four weeks out
Plan food
Cheapest path: grazing board + 1–2 platters. Sydney suppliers under $200 for 25 guests:
- Glory Days Grazing — medium grazing box $145, fits 15–20 grazers
- The Curated Board Co — small box $95, medium $165
- DIY (Costco run) — charcuterie meats, cheeses, crackers, dips, fruit — $80–$120 if you assemble yourself
Pair with 2 hot platters (pizza from Crust or a local Lebanese caterer for $60–$80 each) and you're feeding 25 comfortably for $200 total.
Order tableware
Kmart's themed plate/cup/napkin range is $5–$8/pack each. Spotlight's "in the natural" range (kraft + sage + terracotta) photographs beautifully and feels less "kids party". Budget $40–$60 for full tableware.
Pre-plan the photo concept
If you're DIYing photos, scout your backyard light in advance — ideally a softly-lit corner around 11am or 4pm. Test phone tripod placement now, not on the day.
Three weeks out
Send invitations
Canva has 1st birthday templates — $0–$15. Send via text or WhatsApp. Ask for RSVPs by 1 week out so you can confirm catering quantities.
Cake smash outfit + birthday outfit
Cotton On Baby + Kmart cover both for under $60 combined. Wash them ahead so they're not stiff or smelling new.
Two weeks out
Confirm cake + decor delivery times
Send us the address + delivery window (we usually deliver 2–3 hours before your start time). Confirm with the cake maker for collection or delivery.

One week out
- Confirm guest count and final RSVPs
- Buy disposables (plates, cups, napkins, cutlery)
- Stock drinks (water, juice, beer/wine if adults — budget $40–$80)
- Charge phone + tripod, clear phone storage
- Cut lawn, sweep patio, set up shade if needed
- Print one "from 0 to 1" photo wall (Officeworks 5x7 prints + simple twine)
Saving smart (without it looking cheap)
Where to save
- Tableware: Kmart over premium party shops — nobody looks closely at plates
- Photographer: Phone + tripod + good light beats a $400 photographer for casual home parties (save the photographer for the wedding)
- Favours: Most kids don't notice if there's no favour bag
- Flowers: Skip florists — one $30 bunch from Coles plus eucalyptus from your garden looks great
- Drinks: A drinks station with one cordial and water beats stocking 4 different drinks
Where NOT to save
- The cake: The cake is in every photo. Pay $100+ for one done properly.
- The backdrop: A $20 paper backdrop looks like a $20 paper backdrop. Hire one or skip it entirely — don't half-do it.
- The balloon garland: Cheap supermarket balloons look chalky in photos. Either hire it or pay for premium DIY balloons.
- Drinks for adults: If you're inviting adults, having decent wine or coffee makes them feel hosted.
Budget variations
Ultra-budget ($450 total)
Skip the decor hire. Use $80 DIY balloon kit + Kmart paper backdrop + spray-painted foam plinth. Save the $300 decor budget. Food becomes $150 DIY grazing + cake $100 + tableware $40 + outfit $60.
Mid-tier ($1,200)
Add a photographer ($300–$400 for 1.5 hour mini session) and a marquee tent hire ($100–$150). Upgrade cake to $200, food to grazing-board + caterer for $350.
Premium ($2,000+)
Add a stylist for the cake table, professional photography (full session $600+), catered hot food, helium balloon ceiling cluster ($150–$250), custom cookies + favour bags. Often hosted at a venue rather than home.
Sydney-specific tips
- Council rules — if hosting outdoors and inviting 30+ people, check your council's noise/large gathering rules
- Parking — advise guests to park considerately on your street and notify neighbours
- Summer heat — backyard parties from December–February need afternoon shade (after 3pm direct sun is brutal in Western Sydney)
- Bin day — schedule parties so bins are empty Sunday morning, not full to brim
- Insurance for the trampoline — if you have one and kids will use it, double-check public liability
