I remember watching a documentary about Australia before. I think they showed an animation of Australia drifting to where it is now, and I think when Australia was 10 degrees further south, most of the country was shaded green instead of the brown color it is today
Doubt it. Although it depends what you mean by snowy as an aussie.
Think of Western Europe and Britain in terms of snow. The Victorian Alps could be very snowy though.

Well being right in the route of the westerlies Australia would naturally become more moist and green looking not necessarily wetter overall. The north would be like current day Mediterranean Australia and Subtropical Central sections of Queensland but maybe wetter.
Indeed! Snow as far north as Perth, and almost Tierra del Fuego-like weather in Hobart, and borderline tropical/subtropical for Darwin would make Australian weather much more interesting.
However, pity Melbourne as their notoriously unpredictable weather will get even more unpredictable. Here's how I'd imagine it working out: think one spring or autumn day it was 60s or 70s, then the next day it struggles to get above freezing and there is heavy snow falling over the place and stuff. Or imagine a summer day where it was 90s then the next day it plunges to a high of about 50F then the day after would be 70s. Or picture a winter day where one day it was 20s, and then next would be 50s or 60s...
Canberra will probably be continental. The real Canberra to my knowledge is the only major Australian city to record below freezing temperatures every winter.
Darwin & Cairns might be a coastal desert (like the persian gulf cities)
Sydney, Newcastle & Melbourne would probably still be oceanic but just colder (maybe like Vancouver)
Hobart is like southern UK.
Perth would have Mediteranean climates.
Gold Coast & Brisbane would have humid subtropical climate.
Australia would be far more inhabitable climate wise as a whole were it about 10 degrees further south, the north would be mildly warm for much of the year and I think overall rainfall in the country would increase (though areas with a summer peak rainfall would likely decrease overall) with the greater influence of mid-latitude lows.
I think most cities south of Brisbane would have at least the occasional snowfall, in Hobart and Canberra it would probably be quite frequent in winter. Melbourne might have climate averages similar to Victoria, British Columbia. I suspect Sydney and Brisbane could become drier due to the reduced warmth and storm activity. While Perth and Adelaide would maintain a Mediterranean rainfall pattern it would also become much wetter over a longer period of the year and rainfall would penetrate further inland. Places in the far north like Darwin would also get a few days each winter with precipitation from frontal systems.
Darwin would be hammered by cyclone as there is now much more water for cyclone to build.
