I looked at the flood levels on a previous thread about a tunnel portal near UQ Lakes:

@mocon31

With the flooding, BCC Floodwise Report gives a 1% AEP / 100 ARI (i.e. 1 in 100 chance each year) level of 8.3m AHD and Jan 2011 is shown as being 7.9m AHD. For comparison, the Brisbane Metro Cultural Centre underground station was designed with a 150 ARI immunity but would be “inoperable” at 75 ARI. The existing UQ Lakes station is between 6m and 8m AHD so would also close at a similar flood extent, even if the tunnel is designed for greater immunity.
