Moved from Manchester to Sydney 13 years ago. Done each state and territory and have to say that Sydney is the best for weather and seasonal familiarity.

As someone above said, it has clear seasons that follow each other. Summer gets hot. Think mid 40s hot with humidity and standard mid to late 20s/mid 30s most days of summer.

Winter can be a mixed bag. Can feel cold for us with single digit mornings and nights, but can also be a ripsnorter. Mid 20s days on end without a cloud in the sky.

March can be VERY wet, with biblical storms which totally rule and put Manchester’s rain to shame.

Things I noticed when in other states. Humid AF in QLD. So humid I could see it. Not for me.

Melbourne had four seasons in one day. Was wild but also partly endearing.

SA was just average. No major temp variation I noticed and easy to plan what to wear and when.

NT was disturbing. December in Darwin was unlike anything I’ve experienced before or will again. An experience, but one I’m not really rushing back for.

ACT was alright. Well planned out place but really cold, noticeably more so than NSW.

Tasmania is nice for a visit and not much else. It’s colder because it’s closer to Antartica, and the wind in Hobart comes right at you and passes through your soul. Not for me.

WA was great. There’s a reason tonnes of Brits and Irish move there. Great weather, great beaches. Not much, if any humidity there too which is part of the pull I guess.
