This is unlikely to be either make or break.

TGA registration was finalised in June, 2017 and didn't have much impact on the share price either way at the time.

Given that the product is already registered it's hard to imagine what possible positive news could be coming about TGA registration. Perhaps that we still have it? Or are getting it again? There's really nowhere better to go from having registration already.

But given that getting it didn't make a positive difference to the share price, I wouldn't expect there to be much negative reaction even if the worst-case scenario plays out and TGA registration is revoked.
