This is a quote from Blair Trewin, Climatologist with the BoM.
I know what you are asking and the answer is that I paraphrased 'shift' for 'axis'. No harm done.
'I've done a search for sub-10 maxima in the tropics - haven't looked in detail at site records yet. Defining the 'tropics' is trickier than I thought because the Earth's axis wobbles a little over time and the position of the Tropic of Capricorn moves at a rate of a few metres per year - and Longreach is so close to the line that, on its present position, the current site is in and the old site is out, but the old site was probably in at the time it got its sub-10 in 1908. For the purpose of this exercise I've used the current value (quoted in Wikipedia) of 23 deg 26 min 22 sec.
There were 13 sub-10 maxima in the tropics yesterday, 8 in Queensland and 5 in the NT. Before yesterday there had only been 12 in the entire record (and no more than 2 on any day), all but one of them in the NT (5 of them at Yuendumu, which also scored yesterday).
Tennant Creek Airport's 8.0 is the northernmost sub-10 max ever in Australia, albeit only just (the old record was at the old PO site, 900 metres to the south). Camooweal's 9.8 is the northernmost recorded in Queensland.
Three sites broke Yuendumu's old record (8.2) for the lowest max ever recorded in the tropics, with the lowest being 7.7 at The Monument (near Mount Isa).
Outside the tropics, Applethorpe's max of 4.9 is a Queensland record for June.'
