Mmm, 100°F is 37°C or thereabouts . . . South Africa is (apparently) similar to Australia in a lot of ways, temperature wise I looked up the following for Brisbane, the capital of the State of Queensland and, as it's still spring here, these are the average temperatures . . .

Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec
29° 29° 28° 26° 23° 21° 20° 22° 24° 26° 28° 29°
these are the maximums (averaged)
21° 21° 19° 17° 13° 11° 10° 10° 13° 16° 18° 20°
these are the minimums (averaged)

. . . it does get hotter west of us (west of anywhere really, ) . . . but, the record in Australia is held by Queensland, with the Highest Recorded Temperature being at Cloncurry, 53ºC in 1889! And of course, there's Marble Bar (Western Australia) a town that holds the record for the longest 'hot spell' . . . Highest Average Monthly Temperature, 160 days/year over 37.5ºC!

And for those interested to know, it does get COLD in Australia, the Lowest Recorded Temperature was at Charlotte Pass, New South Wales (in the Australian Alps) of -23ºC in 1994!

I was working in a ski resort nearby Charlotte's Pass in 1994 and I can confirm it was effing freezing!

Cool Copago!

Brrrrrrrrrrrrrrrrrrrrr

Eng, I'd just like to point out that people living in Brisbane are spoiled. (And I can speak with authority because I lived in Brisbane for 26 years!)
Ipswich is only 20 miles west of Brisbane, but it's like another world, climate-wise. It's always at least 5 deg hotter in Summer, and 5 deg colder in Winter. Temps regularly sink below 0 in Winter, with the coldest I can remember being -7!

Houses here are not built for the cold weather either. I find it all gets a bit much for me in January when it could reach 5 degrees C. My present flat is fairly easy to keep warm (and cool in summer... well over 30 sometimes), but some places are really draughty , and you have to have an electric fire on. I use an electric blanket and several quilts in winter, but I am a cold footed one, like Leau. I still find it infinitely better than England. I was there last Christmas and still remember the shock at Heathrow as the bitter wind hit me.It snowed too Yuk!!

I live on the coast in West Aust and there is no need for central heating. Reverse cycle aircon for the main living area and small electric heater to take the chill off the bedroom and a fire outside when having a bbq or drinks. At work, out on the edge of the desert, good central heating would be appreciated in the cold months
