Our kitchen mixer tap is leaking (cracked body) and needs replacing. Unfortunately, the hot water stop tap below the sink does not appear to stop the water flow. Seems like something isn't working inside. The cold water one is fine. I've replaced the mixer before so I know the stop tap was working previously. Just wondering if there is any way to replace the mixer. i.e. can i stop the flow of water to the hot water unit and drain it before replacing the mixer? Will this damage the hot water unit? The unit is about 3 years old.
Any other suggestions appreciated...

What about the tap at your water meter?? is it an underbench hot water unit? some more details or a pic of the setup might help more?

Picture of the hotwater unit. The top hose going into the unit is marked as inlet and bottom tube (central to the unit) is marked as outlet. The other tub on the bottom is the gas pipe.
Picture of stop taps below sink. The left is the hotwater going into mixer, the middle is the cold water going to mixer. Left stop tap no longer works.
The main meter tap will stop the water to the house, however I'm not sure what would happen if i did this and then left one of the hot water taps on. I figure it will drain the hotwater system to a point so I can do the repair work. The other option I thought was to shut the outflow from the hot water unit, however way the taps are setup, I have no idea what will shut it off.

No, turning of the mains tap won't drain the hot water system when you have a hot tap on, you'll get a little dribble then nothing. Same as the cold side.
So all good! Turn off at mains, then go ahead and fix!

I agree with Seano, turn off all the water at the main, and then fix the mixer tap and replace the washer in the stop tap too. You can if you want to close the stop tap on the HWS as well for an hour or 3, but don't leave it like that for a really long time unless the electrical supply to the HWS is also off.
Having lots of old towels under the sink will help in there.
