Advice regarding travel insurance (Kuala Lumpur)

Hi everyone,

I'm moving to KL in August for at least two years, and was wondering what to do about buying travel insurance? I will be doing lots of travelling around via planes and also want to go scuba diving...am I right in thinking that I can't get insurance from the UK if I'm going to become a Malaysian resident?

Any help you can offer would be greatly appreciated!
