Hi, we've used a combination of Frontline and a 'Killtix' collar on our two dogs when living in Townsville, Qld. We found a topical application plus a collar necessary as it is hard to keep our dogs out of water.
WARNING always read the labels. For example, Frontline states it is only effective against paralysis ticks for the first two weeks after treatment. (Meaning during tick season you have to reapply every fortnight- EXPENSIVE but worth it!!) Also some treatments can not be used with others and they don't refer to brand names but the leading chemicals.
We had friends tell us they found Advantage useless in our area so we always used Frontline?? Perhaps check with a local vet of the area you are travelling into & they will let you know what tick prevention works best in that area.
