There are rumours going around that Suncorp has select Southpoint at South Bank as its new headquarters. Construction has not even started, so it will be a long way off. (The other option Suncorp was looking at was 480 Queen St, the site of the proposed but abandoned Trilogy Tower.) I suspect that this will add to the value of apartments in South Bank and some in South Brisbane.
Update: Tuesday 29 November: Rumour confirmed as correct.
