G'day Marty Bhoy,

For what it's worth, the version collected in Australia ... presumably uses the same standard music-hall tune ... so here are the published chords in Alan Scott's A Collector's Songbook, Bush Music Club, Sydney, 1970 - where the tune is in the key of C (transpose to suit ...):
/C    /       /G7    /C      |

/C    /       /G7 D7/G7    |

/C    /       /      /Am    |

/C    /       /G7    /C      |

Regards,

Bob
