Being on the east coast you do have a lot of potential options, as you stated you can connect in the DFW/IAH hubs or even with AC at YVR. Unfortunately, none will be easy.

You may have some luck connecting in Asia. It is a lot longer journey, but finding 3 J seats is definitely easier this way. For example Cathay through HKG, or Singapore via SIN. Or even, connecting the long way around in DXB or AUH.

Another potential is flying in F to HNL then flying on HA J to SYD. HA can be booked with AA miles or VA points. Fiji is another potential connecting point. FJ and HA J class are not the best products in the world but still nice.

If you can snag a single J award on VA, they do tend to open up award inventory at the last minute if seats are empty. So you could possibly snag more seats at the last second. A bit risky though, as these flights can be full. IME most of the other airlines on this route will not open up J award space at the last minute.

I believe you need to be an Australian or NZ resident to open a VA (Velocity) account. So, you may not be able to do this.
