You have my sympathy, John. It's not a laughing matter when they give you the heebie-jeebies. I detest them. We get our share in the house (though the number has decreased since I fixed a wonky fly screen on a bedroom window) but I use the 'catch and release' method rather than despatching them to the hereafter. Now is the time that they'll become more obvious as it's coming up to their mating season, so they tend to wander around much more than at other times. From experience I'd say from Novemeber through to the end of January is the peak time, though I've had them turn up in late May on occasion.
To capture them I usually use a 'bug catcher' (sometimes available at K-Mart for a couple of dollars) though sometimes these are a little small - albeit that the spids usually tuck in their legs to accomodate me. The largest beastie I've had to contain required a 2 litre icecream container, and even then it didn't quite fit. Eeek!
At least around where I live such monsters are rare.
Good luck - he'll turn up again soon.
