This would make Larry a category 4 on the Saffir-Simpson scale.
Remember: ATCI uses maximum gusts...which, with 280 km/h being 175 mph....we are looking at approximately a 145 MPH system (1-minute sustained).
A reminder for australian systems: DO NOT USE DVORAK OR JTWC FOR STRENGTH MEASUREMENTS. Dvorak is often inaccurate for SH systems (for whatever reason...who knows why) and the JTWC only updates every 12 hours, and they are often very very wrong.

It is fine as it is, the Aussies won't even think of the SS scale when looking at TCs.
Re the post above: The scale works on gusts and not sustained winds.
Edit - Several posts above now but you know which one I mean.
