From Adelaide Independent newspaper:

How to interpret data

After digging to a depth of three metres last year, Melbourne scientists
found traces of copper wire dating back 100 years and came to the conclusion
that their ancestors already had a telephone network more than a century ago.

A Sydney archaeologist dug to six metres, finding traces of 130 year old
copper wire and concluded that NSW already had an advanced high-tech
network
30 years earlier than Victorians.

One week later, the SA Minister for Information issued a media statement:

"After digging as deep as 10 metres in pasture near Tanunda, we have found
absolutely nothing. This proves that 150 years ago, South Australia had 
already gone wireless."
