Again just tried the ping, and no connection, total loss of packets.
May be able to get to some BOM servers rather than the main front end,
but something not working.

I suspect that bom.gov.au is blocking ICMP requests, probably as there are services they wish to protect...

xxxxxxx@gastron:~$ ping bom.gov.au
PING bom.gov.au (134.178.253.144) 56(84) bytes of data.
^C
--- bom.gov.au ping statistics ---
8 packets transmitted, 0 received, 100% packet loss, time 7055ms

But, www.bom.gov.au on other hand is working fine...

Note the differing IP addresses reported by the two services.

Also Keith, I'm pretty sure you can't ping a web page directly i.e. what you posted below is expected behaviour...
