Bloody heck: it's only gonna be 25 on Saturday! That's not right. Christmas day is supposed to be hot. I won't be able to enjoy the roast lunch without the stifling heat and humidity.
I wonder if they'll mind too much if I set up my wind trainer at the table? It should simulate a proper Aussie Christmas - hot, sweaty, uncomfortable. Might have to tape up the wind veins though, don't want any cooling breeze ruining the sensation.
