Spoke count seems a bit low at 32 but that's my prejudice.

You get what you pay for. In a positive way.
The frame looks quite nice. If it fits you both and if its stiff enaugh and "rideable" (can you test it?)... give it a try.

The components are either entry level or not branded at all. Keep an eye on them whether they are capable to take the bigger loads and forces of the tandem use. The 32 spokes were mentioned. With a decent quality, properly assembled with a matching hub and rim - it might work. One of those "if's" missing - can lead to problems. The mechanical disc breakes wouldn't be my favorites: Not on a single bike and certainly not on a tandem. Especially the long cable to the rear break leads to bigger hand forces and wouldn't meet my demands here.
The rest might be tested on the manageable risk of the 400$ ;-)

That does look like a good starter tandem. Somebody was selling new ones here in SoCal a while back for pretty cheap as well.
I contacted the company to verify the crankset and they confirmed they are stamped and not removable chainrings.
So just beware, when the chainrings eventually wear out, you will have to buy all new cranks.
Replacement tandem cranksets can run a lot $ unless you find something used or willing to tap/drill out standard sets.
Enjoy it for now!

Oh boy ... I see the appeal. And as hard as it might be to pass it up, that is what I would do. The hi-ten (steel) fork is the first strike. Unknown is the dropout spacing of the rear axle. Tandem spec is 145mm. I would even say 140mm would get this one over the finish line but my guess is it might be 135mm (MTB) because with that gearing and those tires the designers aren't thinking there will be much stress on the running gear. New, these bikes are $899. That is just astounding and not in a good way. The problem is, for the $400 ask for this particular bike an older (but not too old) Burley Samba could be found and it would be 5x this particular model in value. A Trek T900 could easily be found for $400 and with not a lot of work could be made every bit as badass looking as the Polygon but with a fair amount more quality underneath.

Your in Australia, I don't know how many tandems are in Australia. In the U.S. I would pass on the polygon, you can find a better used tandem for about the same price.
