Our Australian company is looking to expand our client base in Asia, we currently have clients in HK, mainland China and Singapore.

I would like to setup meetings with potential clients (both businesses and individuals) in Bangkok throughout the year between my other trips.

Looking at the Melbourne consulate website a 12 multi entry visa looks like the ideal choice.

As we are yet to establish any Thai relationships, so I do not have a Thai company to sponsor the visa.

Is it possible to gain a visa based just on our Australia company wanting to attend Thailand and offer our services?

I suggest you contact the consulate to find out what the actual requirements are to get a multiple entry non-b visa. They should issue it for a Australian company without any business contacts here already.

Thanks ubonjoe currently out of the country on business, will give them a call on my return.
