Planning and Infrastructure Minister Alannah MacTiernan today officially opened Australia's first such facility in the former Parcels Office at Fremantle.

"I am firmly committed to ensuring our public transport system caters for cyclists as part of its passenger mix," Ms MacTiernan said.

"Fremantle Station attracts about 140 cycling commuters every day, and currently has 16 lockers and 25 U-rails for secure bicycle parking to cater for this growing trend.

"Today we have added a further 90 U-rails in a covered and locked facility, which will be under 24/7 video surveillance.

"While it is on a much smaller scale, the concept is based on the practice in European cities like Zurich, Copenhagen and throughout Holland, where thousands of bicycles are stored in a secure area and supported by on-site repair and related facilities.
