Sydney has consistently been perceived as the most expensive city to live in Australia. However, this is no longer the case according to recent data. The major harbour city once held the mantle for having the most expensive median house prices but has lost that title to Byron Bay.

In 2026, Byron Bay is often more expensive than Sydney when it comes to short-term accommodation and specific "lifestyle" costs, though Sydney maintains a higher overall cost of living for residents. Byron Bay has evolved into an ultra-premium global destination, with a median house price that frequently rivals or exceeds Sydney’s most affluent suburbs due to its limited housing supply and celebrity appeal. For travelers, the cost of a mid-range hotel or a meal at a popular cafe in Byron can be significantly higher than in Sydney's CBD because there is less competition. However, Sydney remains more expensive for day-to-day essentials like public transport, parking, and high-end professional services. While Sydney offers a wider range of "budget" options due to its size, Byron Bay has essentially "priced out" the budget traveler, making it a place where "luxury-core" prices are the baseline for almost every visitor experience.
