How big are the speaker cables?

Size can vary from skinny bell wire (yuk) to cables the size of a hose-pipe 

A photo would be helpful.

They are pretty skinny, its not a very fancy system. Maybe I should invest in some good cable as well?

Is there carpet?  If so just lift the edge and tuck them in underneath the carpet right at the edge.

Cant do that, its glued down.

As  general guide, spend about 10% of your hi-fi budget on cables.

Who needs expensive audio cables?

"If the speaker wire packaging lists a "gauge," 12 to 20 gauge would be fine; the higher the number, the skinnier the cable's metal conductors will be.
So 12 or 14 gauge might be too thick to squeeze into the speaker and receiver's connecting holes, but if you need to run long lengths, more than 25 feet, go for the thicker stuff.
Trim away enough strands at each end to squeeze the remaining strands into the connectors' holes."

If you can see it, get capping. There is some reasonable options at bunnings to hide speaker cables in the electrical area. Then you can paint it the same as the wall or baseboard and it will "disappear"

There's normally a small gap between the skirting board and where the carpet is attached to a thin wooden trim which is the same thickness or a bit less than the underlay.  So you can use a knife or similar and just lift it right by the skirting board, creating a small gap, tuck the cable down into the gap and the carpet sits back down on top.  I've never seen carpet laid any other way, although I suppose it's possible.

Totally. Put a damn plug on the cable that will fit the terminals.

For aesthetics, I would agree with the suggestions of capping/plastic trunking and tucking under the carpet as suggested above.

For a slightly less aesthetically pleasing result you could also try these:

Available in difference sizes to suit your wire gauge. Black option available in certain sizes too.
