If the reach column is 0, then you are not seeing the remote servers.  You 
should see 377.  Look for a network or connectivity issue.  Can you ping 
the remote servers?  Ask them an NTP query like:

  ntpq -p wirelss.org.au

By the way, that query doesn't work for me, so are you sure that server is 
running NTP?  Do you have permission to access it?  You might be better 
off with "pool" servers:

  0.pool.ntp.org
  1.pool.ntp.org

Cheers,
David
