Victorian Government has announced major changes for public transport for kids.
Starting 30th January 2017, the age at which a child must start carrying a myki will be lifted from four to five, Premier Daniel Andrews announced.
A Myki child ticket provides a discounted child fare which is 50 per cent of the full fare. Kids will now need a Myki child ticket when they start school at the age of five.
The government will also lift the eligibility age for a child myki ticket from 16 to 18.
The change means young people will have access to concession fares until they are 19, even if they aren’t at school or university.
For a 17 or 18 year old working instead of studying, the shift will save them as much as $800 a year.
In an added bonus, 17 and 18 year olds will now be able to use a learner’s drivers licence or Proof of Age card to prove their eligibility for concession fares.
This change will save up to 10,000 fulltime students the hassle and cost of buying a PTV School Student ID.
Minister for Public Transport Jacinta Allan said, “These changes will save a lot of money and a lot of hassle for families using our public transport system.”
CONCESSION CARD HOLDERS PAY LESS ON WEEKENDS
Concession card holders now pay reduced price after the new concession cap was introduced on weekends. Under this new concession, the cost of Zone 1+2 travel on Saturday and Sunday has dropped from $3.90 to $3.00.
