a ‘tourist visa’ is not one month, it’s 60 days, extendable in normal times by a further 30 days for 1,900 baht.
I think, because you say you are Aussie, you’re referring to a Visa Exemption which gives 30 days stay and can also be extended for a further 30 days for 1,900 baht. Note that was pre-Covid and no one really know anything about what might happen once the amnesty is over.
