Latitude-wise and longitude-wise, the world has been moved this way:

Eurasia, Oceania, and Africa: 45 degrees south and 135 degrees west
North and South America: 25 degrees south and 120 degrees east
Australia, New Zealand, surrounding islands not including those which are governed by Australia and NZ but are too far from said countries: Just replace S with N and not change the longitude
Antarctica and subantarctic islands: Same thing as above

Maybe give us a drawing of the alternative map to give us more on an idea.

How about discussing what aspects of climate would have been different 20,000 years back when TAS and New Guinea were joined to mainland.

Great Divide would have had a bit more altitude to mountain tops from sea level. Better snow levels. or would this be contradicted by land in the Great Australia Bight.

Would that extra land in Great Australia Bight stop them horrible HIGH's, and make the SA deserts even hotter in summer, which in irony may lead to lower pressure and more thunderstorms?

From a local Illawarra perspective the escarpment may have been able to wring a bit more rain from ECL's, but countering that the coastline would have been further out, but the East Coast shelf drops rather quickly so maybe not that far?

What would the climate of the land bridge between Tasmania and Victoria would have been like? a dry low grassland, or a forest.

Perhaps places that are now along Tasmania's north coast could have been rather dry?

Bear in mind that 20,000years ago there may have active volcanism in VIC, and the maybe the land bridge?

The land bridge between QLD and New Guinea, plus most of the Barrier Reef platform - as dry land would that increase QLD thunder activity? again the heating aspect, or leave it as a dryish Savannah plain.

Would more warm water be carried southward along Australia's east coast from Queensland to Tasmania?

If I've worked it out correctly an alternative version of the original post would be move Asia, Europe and Africa south by 45 degrees so that Europe, Tibet and China are all roughly on the equator. Move South America a little south so that Florida is on the equator, and then west so that the west coast of the US lines up roughly with Japan. Around Alaska and Siberia there would be some significant overlap I think. Then mirror Australia and Antarctica into the NH, with Australia roughly in the middle of the resulting mega ocean.

Much of Eurasia would become a huge desert. During the NH monsoon much of the tropics in this region is land, and the ocean to the south would be cool, so supply of moisture to the monsoon would be weak. The Himalayas on the equator would also provide a substantial block to northward moisture flow and the desert to the north would be in the zone of maximum summer heating. South America and south Africa would be as close to south pole as Greenland so presumably gain ice sheets. Although normal maps make Greenland look quite large compared to these locations, the distortions of projecting a sphere onto the flat actually make the north tip of Greenland similar to the south tip of South Africa.

Australia being moved away from the Asian land mass would have a weakened monsoon, and the NW (or SW in the flipped version) would become more arid. Antarctica would still be surrounded by a good ocean and the polar NH circulation would probably be very similar to the current polar SH circulation. With the Pacific combined with the Atlantic the walker circulation might be stronger. Tropical activity would peak on the east coast of North America, and instability would be translated towards the NE, possibly onto the West Australian coast. At a guess the flipped version of SW Australia would become quite a lot wetter, and the east coast would stay about the same with weaker tropical/monsoonal type influence, but enhanced trades, and instability downstream of North America.

What about the original version in the original post? How do you interpret it?

Major overhaul:

Eurasia, Oceania, and Africa: 45 degrees south and 135 degrees west
North and South America: 25 degrees south and 115 degrees east
Australia, New Zealand, surrounding islands: Replace S with N and then move by 275 degrees west
Antarctica: Just replace S with N and not change the longitude

Would Tasmania have a similar climate to the UK if the Australia continent was placed to the south east of Tasmania?

In winter, Southern Ocean fronts crossing Tasmania barelling into very cold and dry air being pushed up over the new Australia continent?

Tasmania would have so much potential for better weather if the warm island to the north was out of the picture

Do you mean Tassie could be colder if not for the main island being where it is?

One last change, now that my mind is well made up.

Europe, Asia, Africa, and Oceania- 45 degrees south and 135 degrees west
North America and South America- 15 degrees south and 160 degrees east
Australia, New Zealand, and Antarctica- Change S with N and don't change the latitude

I'm gonna move North and South America 15 degrees south and 160 degrees east. So would 160 degrees west become 0 degrees west and would 159 degrees west become 0 degrees east?

My dream is simple. Leave every continent as is but move Antarctica 20 degrees north towards Australia. The northern extent of Antarctica would reach to about 45 degrees. This would have little impact on our summers with prevailing winds from the east however our winters would be more like Japan's in winter. The sharp contrast in temperatures between the Antarctic landmass and the waters off our southern coast would lead to a very strong jetstream with continuous cyclogenesis. The passing lows would frequently send bursts of very cold polar air over southern Australia which would gain moisture over the slim Southern Ocean (without significant warming) and dump copious amounts of snow over southern Australia. Melbourne's climate in winter would be similar to Niigato at a similar latitude - more than 2 metres of snow annually. I could snowboard every winter weekend on the Blue Mts and still enjoy summers on the beach! How can we drag Antarctica further north?

Personal solution: a 1 degree delay. When it comes to moving continents 135 degrees west, I'd be moving parts of them by 134 degrees instead when it comes to longitudes less than 135 degrees west, and 159 degrees instead when it comes to longitudes less than 160 degrees west when it comes to moving continents 160 degrees east. (This is all because there's 0 degrees west and 0 degrees east.

Turns out I have to do the one-degree delay too when it comes to moving latitudes.

Said delay would apply to the places in the Southern Hemisphere that are in Asia, South America, Africa, and Oceania.
