In 2025, Australian free-to-air TV has been undergoing a quiet but important transformation. Broadcasters like Channel 7 are phasing out older MPEG-2 compression in favour of more modern MPEG-4 technology—offering viewers better picture quality and more efficient use of broadcast spectrum. But what does this mean if you’re in Melbourne or Sydney?
In cities like Brisbane, Perth and Adelaide, Channel 7 has already switched off MPEG-2 broadcasts for its main channel, replacing them with MPEG-4 HD simulcasts. These changes require viewers to have televisions or set-top boxes that support the newer MPEG-4 format.
If viewers in these cities were using older equipment that only supported MPEG-2, they would have lost access to Channel 7’s main broadcast unless they upgraded or retuned to MPEG-4.
At the time of writing, Channel 7 in Melbourne and Sydney is still broadcasting its primary channel in MPEG-2, alongside its HD MPEG-4 simulcast. That means viewers with older MPEG-2-only TVs or set-top boxes can still access the standard definition version of Channel 7—for now.
However, given the network’s rollout strategy across other metro areas, it’s highly likely that Melbourne and Sydney will follow in the near future. So far, no official date has been announced for the MPEG-2 shutdown in these cities.
If you’re in Melbourne or Sydney and you still watch Channel 7 in SD, now is the perfect time to make sure your TV setup is ready for MPEG-4.
Upgrade if needed: If your TV or set-top box doesn’t support MPEG-4, it may be time to upgrade to a new digital TV or a HD-compatible set-top box.
Check your TV’s compatibility: Most TVs sold after 2010 support MPEG-4. You can test this by tuning into Channel 70 (7HD) or 73 (7mate HD). If you see a picture, your setup is likely MPEG-4 compatible.
Retune your channels: Use your TV’s auto-tune or rescan function to ensure you’re getting all available HD services.
