Not being an alarmist,but,,I just watched a news article on telly about an invasion of european wasps in Port Augusta.
These pesky little buggers are a bit larger than honey bees , but have a twitchy flying style, changing direction very quickly.
The problem with these wasps it they like to crawl into open beer & pop cans while your not looking, making your next sip possibly your last, (without urgent medical treatment)
Just be aware , and dont leave open drinks unattended in the Pt Augusta area , and lastly Dont try and kill them , because they put out a distress signal to their mates @ home, and before you know it,,you have a swarm of unwanted guests to keep you company
Not long now eh! 8-[
