You're at 36°19' S Lat 146°50' E Lon in Yackandandah, Victoria, Australia. 100 miles from the coast.
I'm at 32°19' N Lat 86°15' W Lon Montgomery, Alabama, USA, 135 miles from the coast.
Your latitude is more similar to Nashville, Tennessee, and would tend toward colder than mine, however, the proximity of the coast probably tempers your climate a bit. The humidity around here tends to be high most for the year. Mold and moss are issues that we must deal with. I am not sure what the humidity levels are where you live. Humidity will effect how quickly the soil dries out. Otherwise, I expect the treatment of plants would be similar between our to locations.
FYI: I have a few connections to the land down under: My Mother-in-law grew up in Glenelg, just outside Adelaide, and came to the US to get married. My wife's Auntie Chris, lives outside Brisbane. I believe my wife's uncles, Ian and Martin, live in Adelaide, though we have not talked with the uncles recently. Even after 2 generations, the australian accent is still detectable in my children. Many question me why they have a British sounding vowels, instead of the thick southern drawl so prevalent around here. I smile and simply say we home-school.
About 11 years ago, my work took me to Canberra for 3 weeks. I spent a half a day at the National Bonsai and Penjing Collection of Australia (
https://www.nationalarboretum.act.g...al-bonsai-and-penjing-collection-of-australia) It was an inspiration.
Because of our family situation, I could not keep any kind of plants at the house, let alone attempt bonsai. Last spring, our family situation changed, and I decided to start keeping bonsai, and determined to start over the winter. It is the end of winter here, and trees will start the spring sap flow soon. I now have 8 trees that I started over the last week: 1 Eastern red Cedar, pulled from my son's yard. 3 Maples stumps that I estimate are about 10-15 years old, a maple sapling of 3 years, and 4 junipers that I picked up at the local nursery. In addition to these, I have a few clippings that I am trying to root, and a small juniper branch that still has root that I potted to see it it will grow. Right now, everything is on my North facing patio, which has speckled sun being filtered by the trees overhead. I believe this is about perfect for the maples, but may not be enough light for the junipers. At present, I do not have another spot for the bonsai.
