I have been in Australia since February 2019. I can grow vegetables year-round, though I prefer the Winter season over any as temperatures are similar to you here. Some vegetables simply do not well outside of their seasons, so I grow things like lettuce, spinach, beans and more during the Winter. And during the Summer things like chilis, tomatoes, most of my herbs, and many others do better.
Technically I can grow any plant year round, as we never have any frost here. Coldest I've seen it, it in the morning just before Dawn, and that was around 5C. Just that some plants don't do as well, or grow and ripen very slowly outside of their preferred seasons.
We're having a horrible drought here too. All grass is dead, trees look limp and their leaves are curled (when they haven't died and fallen). We're having open fire bans, and recently had a large bushfire in a national park nearby.
I've even given up running sprinklers as the grass can't beat the heat, and I'm only growing weeds for my cow (that she will not eat anyway). She's hay-fed at the moment, but supply is running low, and the last load of hay is pretty horrible.
I feel like we're at the end of this drought though, and fear that rather than gentle rain, it'll come down with storms instead.
I'm what I like to call an "experimental gardener". I like doing things "my way" and see what happens. I enjoy growing plants from cuttings the most, and have requested cuttings from strangers if I saw a plant I liked. In gardening stores I'm always looking for plants that lost limbs that are laying carelessly on the floor, and then ask to take it home. More often than not they take, and I get a new plant for free.
I imagine your seasons are backwards from England as well. We're headed into our Summer slowly, and it's already getting increasingly hot (35C daily). I've bought some chili seeds, and intend to plant them soon (I should've earlier, but better late than never!).
