I doubt this would stand up to a wet season, but keep it in the shed & bring it out on sunny days (in a few months).
I checked Syd/Mel/Adl. Some stores also have a 2m Umbrella for $10. Monty.melb previously listed here.
Also there/s a sand anchor for $4 or $5 depending on your store.
2M is $15.00 in Majura Canberra airport. Low stock though. Someone going there should check out if there is any stocks left.
