For those local/DX stations that may be interested I am operating an experimental analogue SSTV repeater on 50.680 MHz USB with a 1750 Hz tone access. ID Beacons at 30 minutes intervals. Antenna is a half wave vertical and power output is 10-15 watts. Repeater times will be random during daylight hours at this stage. My location is approximately 25 Km north of Brisbane.

Restrictions on Operating Amateur Stations in the Frequency Band 50 MHz to 52 MHz
Licensees of amateur Advanced Beacon and Repeaters stations must not operate their amateur stations in the frequency band 50 MHz to 52 MHz if they cause interference to the reception of television channel 0 VHF transmissions.
In addition, if such a licensee operates an amateur station in New South Wales, Victoria, Queensland, Tasmania, the Australian Capital Territory or the Jervis Bay Territory, the Amateur LCD prescribes certain additional operational and geographical restrictions on the licensee. The licensee must operate in the frequency band 50.000 MHz to 50.300 MHz only, using:
* emission mode 200HA1A and a maximum transmitter power of 100 watts pY; or
* emission mode 1K12F1D and a maximum transmitter power of 30 watts pY; or
* emission mode 4K00J3E and a maximum transmitter power of 100 watts pX.
In addition, the affected station must be at a place that is:
* at least 120 kilometres from a television channel 0 main station; and
* at least 60 kilometres from a television channel 0 translator station; and
* at least 60 kilometres from a television translator station that has inputs on television channel 0.

SSTV repeater on 6 meters
After further consideration the frequency has been altered from 50.680 MHz to 52.250 MHz USB.
Hope that's OK now.

Hate to bear bad tidings, but your service is/was illegal.
SSTV is not a valid mode below 52 mhz due to the protection afforded to Channel 0 service. You can only use SSB CW and low power RTTY no other mode is permitted according to ACMA website and licence details for 50-52.
How about you approach WIA and get the modes changed like we did with the 50-05 to 50.2.
3 cents.
