You can download this particularly interesting Government Gazette here.
Your particular attention is drawn to the increases in Spectrum Allocations made available to Amateur Radio Stations, as well as the increase in legally permitted power... See page 91 of that PDF for the details.
On certain frequencies, the maxmum legal power in dB relative to 1 Watt PEP is... 30 dBW !
That translates to approximately 1 kiloWatt.
On other allocated frequencies, the maxmum legal power in dB relative to 1 Watt PEP remains at 26 dBW
(That translates to around 400 Watts)
