Ours was $12K all up, but it was very relaxed.

$3500 went on the ****tail reception at beachside location
$3000 went on the photographer and photos
$1500 went on the bar (we went waaaaay under budget on this!)
$1000 or so went on hotel accommodation and transport (it was out of town)
$1000 went on the rings (didn't include engagement, that's a separate expense )
$500 on the celebrant
$500 on the wedding, bridesmaid and flowergirl dresses (I made mine, sis's housemate did hers, friend did the FG's)

The rest was sundries I guess. We did our own cupcakes and cake stand, our own music (our playlist, their sound system) and we served a special homebrew during the ceremony, which is probably how we kept the bar costs down!

ETA: Was for about 140 people. Just so you know.

$5K is a perfect dress budget. You will be able to shop really well with that.
