Have a look at this link
http://www.tuu.com.au/clubs_RenderPage. ... ageid=4717The Lost World on Mt Wellington is a great place to visit. I do not know what it is like to be 28 weeks pregnant so am not sure whether it would be too much. The link above specifically shows climbers on the cliffs, but as it says, easy access - so you can get to a very spectacular place with minimal trouble. But I dare say they are talking "easy" for someone that is going to climb a cliff, so again, I don't know whether that is too much.
Are you familiar with Ferntree? Just past (maybe a couple of hundred metres or so, it's been a while) the turnoff to Mt Wellington there is a hotel on the other side, Ferntree Tavern. Park somewhere around here, and across the road there is a picnic shelter (or is it a toilet block, as I said it's been a while). Pass this on a well marked track on the downhill side of this construction and continue on through a lovely, flat forested walk to take you to a turn right, a short uphill section to a waterfall known as Silver Falls. This is definitely possible! Anyone in that area could describe it better for you if my instructions are a bit muddy.
From the top of Mt Wellington there are tracks, I remember one that goes south along the plateau for a while but not sure about any more of it.
A lovely stroll along Seven Mile Beach is always pleasant.
