Which song is playing in the scene where kidman and jackman are drinking together after they've just put the beasts on the ship?

The song in the background is hard to listen cause the volume is very very low.

Thank you

David Hirschfelder composed the score to Australia. Interpolated musical numbers include the jazz standards "Begin the Beguine", "Tuxedo Junction", "Sing Sing Sing (With a Swing)", and "Brazil". Edward Elgar's "Nimrod" from "Enigma" Variations is heard in the final scene of the film.[6] Luhrmann hired singer Rolf Harris to record his wobble board for the opening credits,[7] and Elton John composed and performed a song called "The Drover's Ballad", to lyrics by Luhrmann, for the end credits. Also used in the end credits is "By the Boab Tree", a song nominated for a 2008 Satellite Award,[8] again with Luhrmann lyrics, performed by Sydney singer Angela Little. Little's rendition of "Waltzing Matilda" completes the end credits in some versions of the film. The jazz sound track to "Australia" was performed by the Ralph Pyle big band with clarinet solos by Andy Firth.[9]
