Check the ingredient list on any herbicide bottles you have right now - if it contains glyphosate or the specific chemical being pulled, swap it out. Regulatory systems move at different speeds across countries, so something can be banned elsewhere for years before Australia acts. That's not necessarily a conspiracy, just how bureaucracy works. Different countries have different risk tolerance levels, funding for reviews, and political pressure from industry groups. The fact it's banned in 70 countries does suggest there's legitimate concern though, so it's worth taking the precaution seriously.
Go through your shed and garage, check what you're actually using. For most home gardeners, switching to alternatives isn't a big deal - there are plenty of other herbicides on the market that do the same job. If you've got major weed problems, a local garden center can recommend what works in your area. The timing feels frustrating when you realize something's been used for years, but regulations do tighten up eventually. Better late than never, honestly.
If you're someone who uses herbicides regularly or has kids and pets around, this is actually a good moment to rethink your approach anyway. Mechanical removal, mulching, or those targeted sprays designed for specific plants might work just as well without the worry. I've seen plenty of people stress less about their garden once they switch methods. You don't need to panic, just be proactive about what you've got stored.
