Ok I'll give you Alice is getting close to 200M longer,
BUT
Tulla/Avalon HMSL= not a lot
Alice=1700+
Melbun hot day can get up into the 30s
Alice on a hot day can be WELL into the 40s
Have been there when the air is so hot it's almost too thin to breathe.
Never have known an emergency landing with a well configured and adequately light, heavy anything. They tend to be, as per the requirements of Murphy's law, exactly when the sh*t is deepest.
If anyone can put a Dugong on the hard stuff at Alice AND keep it there in an ISA + 30 day with 500 bodies on board I will definately congratulate you.
Have seen the result of a MAC C141 booboo there some years back. Took ages to get the runway clear again.
Length is definately a consideration but it aint the whole story.
