Some parts of Perth have now become very expensive, especially the beer. An article I have just seen supports this

Ale not so hearty at $17 for a pint
A $17 oversize pint of boutique Belgian beer Hoegaarden at Hillarys pub The Breakwater has taken the title of Perth's most expensive.
Just five years after the most expensive pints in Perth cracked the $10 mark, a survey of 31 Perth pubs by The Weekend West revealed Perth full-strength beer drinkers are now paying an average of $10 a pint.
The survey, which assessed the price of 373 pints across Perth pubs, found The Breakwater's 640ml pint of Hoegaarden had taken over from Leederville pub The Garden, which served the same beer for $18 two years ago.
The Garden has since taken the beer off its menu.
City pub Belgium Beer Cafe came second, charging $16.70 for a pint (570ml) of boutique Belgium beer Leffe - up from $16.50 two years ago.
It was followed by a pint of Peroni, $14, at the Raffles Hotel, Applecross; an Asahi at the Wembley Hotel was $13.80 while a pint of Matso's Mango Beer at The Brook, Ellenbrook, was $13.
Other expensive tipples included a $9.90 middy (285ml) of Asahi at the Oxford Hotel and a $10 schooner (425ml) of French beer Kronenbourg at new inner-city rooftop bar The Aviary.
Perth's most expensive mid-strength was $9.30 for a pint of Super Dry 3.5 at South Perth pub the Windsor.
The survey found the average pint price for a full-strength beer in Perth was $9.97.
