Hi. I'm 34, Australian.

I'm in sakaeo province.

I've been here on a 60 day tourist visa and already extended for 30 days.

I want to stay another few months.

Question1

When you go over the border to Cambodia to come back for the 15 day visa, do you have to get a Cambodian visa or can you just leave thailand and turn around (not enter camb.) and save getting a Cambodian visa for no reason.

If this easy to do on your own and not with a visa run service. As there's are none around here.

Question2

Does anyone know an easy way to get a new 60 day tourist visa in Cambodia. Maybe in poipet or siem riep an agent can do it for a price. Rather than going all the way to pp myself?

You get a 15 visa exempt entry it is not a visa. There are reports of people being warned that 3 is the maximum they can get.

You have to get a visa for Cambodia. You can get a e-visa. See: http://evisa.mfaic.gov.kh/

There are some visa run companies that offer a service from Poi Pet for a tourist visa but you have wait there for at least a couple of days while they take your passport to the embassy in PP.
