could it be 'SIX WHITE BOOMERS'?

    Early on one Christmas Day, a Joey Kangaroo
    Was far from home and lost in a great big zoo
    Mummy, where's my mummy, they've taken her away
    We'll help you find your mummy son, hop on the sleigh

    [Verse:]
    Up beside the bag of toys, little Joey hopped
    But they had'nt gone far when Santa stopped
    Unharnessed all the reindeer and Joey wondered why
    Then he heard a far off booming in the sky

    [Chorus:]
    Six white boomers, snow white boomers
    Racing Santa Claus through the blazing sun
    Six white boomers, snow white boomers
    .. On his Australian run

    Pretty soon old Santa began to feel the heat
    Took his fur-lined boots off to cool his feet
    Into one popped Joey, feeling quite OK
    While those old man kangaroos kept pulling on the sleigh

    Joey said to Santa, Santa, what about the toys
    Aren't you giving some to these girls and boys
    They've all got their presents son, we were here last night
    This trip is an extra trip, Joey's special flight

    Soon the sleigh was flashing past, right over Marble Bar
    Slow down there, cried Santa, it can't be far
    Come up on my lap son, and have a look around
    There she is, that's mummy, bounding up and down

    Well that's the bestest Christmas treat that Joey ever had
    Curled up in mother's pouch all snug and glad
    The last they saw was Santa headed northward from the sun
    The only year the boomers worked a double run
