What to expect
Daytime
Fierce heat in Australia in December. Start early. Hide in the middle. Come out again when the sun drops.
This is not a month for a packed walking itinerary. Water, shade, and a schedule that admits the climate is in charge.
Rain
December is a wetter month in Australia. Showers are part of the deal, not a spoiled surprise.
Waterproof shoes matter more than a rain plan for a beach, especially if a beach is not why you came. Build indoor hours into the afternoon.
Evening
Evenings stay warm.
What to pack
Sun protection
A layer for cooler evenings
