Mystery booming, Wilsons Promontory (Vic)

At Five Mile Rd at Wilsons Promontory recently, I recorded a booming call. Just three of them, a couple of seconds apart. It’s very swampy there, so I’m wondering if it could be a bittern. Can someone please have a listen and check for me? It’s at: https://soundcloud.com/petershute/file-mile-rd-booming It might also be an Emu, there were plenty around, but I’m not that familiar with the call. Anything else it might be? Note that the frogs are very loud in the background, so be prepared if you’ve turned the volume up.
