The Australian media are just desperate for any given talent that comes by that happens to be Australian. They want to feed it into people's brains that Tomic is the next big thing, vulnerable people, people who don't know much about tennis and only watch it once or twice a year. They are successful a lot of the time as these people are also gullible and will believe anything the media throws at them.
"I rest my case. Federer needs to win 28 slams, twice more than Nadal to be in the same conversation with Sampras." A famous quote from helloworld.
