Things to do in Brisbane

I'm feeling all proud and educated and sort of classy as I've spent the last couple of days (apart from the Brewery tour) going round the Botanic Gardens, the Art Gallery and the Museum. I believe that I have expanded my mind and refreshed my soul by wandering round these valued institutions and gardens, occasionally going 'hmmm' and looking intelligent. Besides, they were all free (apart from the Brewery tour).
