Top 6 most dangerous spiders in Australia

Australia’s spider reputation is bigger than its bite, with close to 3,000 species crawling around the country. Considered one of the most spider-filled nations, Australia is home to an array of spiders coming in various shapes, sizes and colours, with some even listed as the most venomous in the world.

In what might be considered good news, the majority are harmless and not all bite. Unlike mosquitoesbed bugs and fleas, spiders only bite as a defence mechanism.  Minor symptoms of a spider bite can include itching and minor rashes.

However, some spider bites can cause serious harm and require immediate first aid, with some even needing emergency treatment and hospital observation.

If you have been bitten by a spider, please contact your closest medical professional
for the correct and most suitable treatment.

Redback spider

Redback spiders hide in sheltered dry places such as mailboxes and garden sheds. Most serious bites come from the female species. As their name suggests, red back spiders can be identified by the red stripe located on the back of their black body.

Mouse spiders are often active during the day time (not nocturnal like other spider species!)
