Climate Zones and Seasonal Planning in Australia: what actually matters to know
Short answer
Visit Southern Australia, including Melbourne and Tasmania, during the summer months from December to February. Plan trips to Northern Australia, such as Cairns and the Great Barrier Reef, between June and August to avoid the cyclone and monsoon season.
From real experience
For a first-time trip to Australia, a 12-14 day itinerary can accommodate Sydney, Melbourne, Brisbane, and Gold Coast.
If choosing between two major routes, Sydney-Melbourne is a strong contender. For travel in December, this combination is ideal. For late September to early October travel, prioritize northern Australia due to weather patterns; southern regions may experience wind and rain. Visiting both the Whitsundays and Tasmania requires careful seasonal planning; Tasmania is best visited between December and February and warrants at least a week-long stay.

For a first-time visitor to Australia, beyond Sydney, Melbourne is a highly recommended destination offering the Great Ocean Road and Phillip Island.
Brisbane itself may be less engaging for tourists; consider areas like the Gold Coast or Cairns for nature and beaches. Tasmania offers beautiful landscapes, especially during the Australian summer (December-February), but requires a car for extensive exploration. Northern regions like Cairns and Uluru are best visited during the Australian winter.

When planning travel to Australia, consider regional climate differences.
Southern Australia (e.g., Melbourne, Tasmania) is best visited during its summer (December-February). Northern Australia (e.g., Cairns, Uluru) is more pleasant during the Australian winter (June-August) due to cooler temperatures. Coastal areas like the Gold Coast have a more temperate climate year-round. Planning based on these seasonal variations will enhance the travel experience.

Cairns and the Great Barrier Reef (Northern Queensland) experience a tropical cyclone and monsoon season from October to April.
High humidity, jellyfish risks, and potential for severe weather disruptions make this period suboptimal for tourism compared to the cooler months (May–September).

The optimal time to visit the Great Barrier Reef is June through August (dry season).
Summer (December-February) carries higher risks of cyclones, extreme heat, high humidity, and the presence of dangerous marine life like box jellyfish, which may disrupt travel plans.
