Hi Tony - you've got a keener eye than me if you reckon there's less Aussie content. Good old Oz is still the magazine's biggest market. As far as being more global, well, I don't think so, especially when I flip through all the back issues. Feature bikes and events from around the globe in pretty much every issue as far as I can tell.
Issue 35 (which is held up at the bloody printers for another two days!) has four events from Oz (the Aussie Nationals from TAS, a motocross event from NSW, a vinduro from NSW and a vinduro from VIC. There's also two events from the US and one from the UK. There's a feature bike from Oz, two reader restos from Oz with a similar number from the US, Europe or the UK.
That was I guess the long answer - the short answer is no, it isn't becoming more global, it is just remaining global like it always has been.
As for mudguards/fenders.......if a story is written by a Yank it's likely to refer to fenders, if it's written by someone from anywhere else it's likely to refer to mudguards.
Regards
Ken
