I read that paragraph and shut out the rest as you were so wrong. After a statement like that the rest also must be dribble or back peddling. You dog it and then praise? it???
The 270, the 280 and the 30-06 all use the same basic case.
The 270 uses a .277 bullet
The 30-06 uses a .308 bullet
The 280 splits the difference with a .284 bullet
The 270's deer bullet is 130 grains
The 30-06's deer bullet is 150 grains
The 280 splits the difference with a 140 grain deer bullet
The 270 launches its 130 grain bullet at 3060 fps
The 30-06 launches its 150 grain bullet at 2910 fps
The 280 splits the difference by launching its 140 grain bullet at 2990 fps

Let me make it clear: Viewed on its own merits, the 280 is a superb hunting cartridge. I'm not "dogging" the 280. If YOU like the 280 and if factory ammo availability isn't an issue, then more power to you. It's an excellent choice.
However, the OP lives in Australia and is concerned about cost and availability of factory ammo.
Under those conditions, there simply isn't enough difference between the three cartridges to justify rebarreling to the 280. Any paper ballistic advantage isn't enough to outweigh the advantage of easily available factory ammo. No animal cleanly hit with a 270 is going to run away thinking "Thank God it wasn't a 280" or vice versa.
Factory ammo may not be important to YOU, but it is important to the OP.
