Laura Blue isn't surprised to hear that hundreds of people are making the move to Melbourne from Sydney each week.

The 27-year-old publicist jumped ship for a job in May last year and says many of her friends have expressed a desire to follow.

Laura Blue loves Melbourne's cafe culture and general 'good vibes;.

"Maybe they're just thinking Melbourne is better than Sydney," she ponders, insisting she is no traitor and is missing the Harbour City's views and beaches.

But Melbourne's public transport system, cafe culture and general "good vibes" are keeping her down south.
