Short answer: Yes — many affordable designer‑inspired (aka “dupe” or indie reinterpretation) perfume sellers do ship to Australia, but it depends on the specific retailer and there are a few things you should check before ordering.

What to check before you buy

• Shipping policy: confirm the retailer explicitly lists Australia in its international destinations and shows shipping cost/estimated delivery time during checkout.
• Customs, taxes and duties: imports into Australia may incur GST (10%) and/or duties on higher‑value parcels; some sellers declare lower values (not recommended) — assume you may pay extra on delivery.
• Prohibited/regulated ingredients: fragrances with regulated animal extracts or other restricted ingredients can be held up; reputable sellers note compliance with local rules.
• Returns and guarantees: international returns are expensive — prefer sellers that offer samples, decants, or satisfaction guarantees.
• Authenticity and safety: “designer‑inspired” are legally distinct from brand counterfeits, but quality and safety vary — read reviews and check ingredient transparency.
• Tracking and insurance: choose tracked and insured shipping for higher‑value orders.

Where people commonly buy

• Local Australian stockists and independent sellers (fastest, no import hassles).
• Global indie perfume houses and decanting services that explicitly ship to Australia.
• Marketplaces (Amazon.au, eBay) or international shops that offer international shipping to Australia.

Practical tips

• Try decants/samples first to avoid wasting money on a full bottle.
• Compare total landed cost (price + shipping + likely GST/duty) before checkout.
• Prefer sellers with clear labeling, good reviews, and tracked shipping.
• Expect longer delivery times and possible customs delays for cheaper international options.
