We spent one night at Tannum on the Beach. While the view was spectacular, the room was poorly maintained (e.g. shower tap came off in our hand, bathroom sink tap leaked, kitchen sponge well worn, broken door latch, etc, to name a few). The 'kitchen' was very limited too.
I grew up in this area and remember when this motel was built. The decor has not been updated since construction and the rooms are rather tired and worn as a result.
We paid $190 for a family room for one night. Knowing the location, this was actually my first choice of accommodation in the area so I was thrilled when they had a vacancy for a family room on the date required. Next time we're passing through, I'd be inclined to book further in advance and try other local motels in Boyne/Tannum.
