He recommends hunters buy their licence online on the Fish & Game website. An adult licence costs $94 and a junior licence is $21.
Hunters should also familiarise themselves with the rules for the region they are planning to hunt in.
"The rules are different depending on which region you are hunting in, so you need to read the regulation book you get when buying a licence," Sowman said.
Sowman said everyone who bought a hunting licence was helping to improve wildlife habitat.
"For a licence to be valid, it must display a habitat stamp. The money raised from stamp sales goes toward protecting and saving wetlands.
"These places are fast disappearing so saving them provides great habitat for native birds and fish, as well as game birds.
"The best bit is you don't have to be a hunter to buy one. If you care about saving wildlife habitat, then buy a habitat stamp safe in the knowledge that the money helps fund many worth environmental projects."
The game bird season runs until August 26.
