Yea, most of it is desert! and the bits that aren't desert yet are on the way there with the drought we have been having.... And then when the sea levels rise more land will be lost because tides in rivers will rise too, most of the coastline and low area's will be flooded, So that's even less land...
And then we have the ethnic tensions which have been getting worse in Australia of late, But the funny thing it is the Muslims who are stirring this stuff up!!! Building "islamic schools" with 8 foot brick fence's around them, Building segregated community's, And literally taking over suburbs with crime, drugs, violence etc... it wouldn't be an unfair statement to say 80% Young Arab Muslim's in Sydney and most other capital citys of australia cause trouble... I know this first hand!
I dont think the Maldives will be that welcome here... Our public transport system is falling apart as it is!!! Our roads are totally inadequate... and petrol prices vary by more than 60 cents a litre from suburb to suburb!!!
They would have more chance of "moving into" a Muslim nation such as Indonesia, Any of the Arab Countries etc....
