What are my options to get help?


Australian research has found up to 10% of Australian children and teenagers have some “sub-clinical” symptoms of Gaming Disorder and Internet Gaming Disorder that would put them in an “at risk” category. If you feel your child is in this category, but the matter is not yet urgent, you may like to take a look at:

  • Brad Marshall’s book “The Tech Diet for your Child and Teen” found at all major in store book retailers or at

  • The parent tutorial video series, developed and presented by Brad Marshall for parents seeking strategies to better manage their children’s tech and screen use. This can be purchased at


Aussie research has also found that 1-3% of Australian children and teenagers have a diagnosable Gaming Disorder. If your child is in the more severe end, or if you are unsure and would like an expert opinion, you can make a referral to The Screen & Gaming Disorder Clinic for assessment by a professional, by completing the form at the bottom of this page. 


After your assessment you will be offered treatment options (if needed) which could include a range of child counselling/therapy, parent support sessions, or parent and child relationship sessions delivered by our experienced team.

What if I live outside of Sydney, or internationally?


For many years we have welcomed referrals from all over the world! We offer video consultation to those who can’t travel. It may sound a bit odd offering a child with gaming/screen issues a video consultation, but ironically in this post-COVID 19 world children often do better with this than adults. 


Medicare rebates for video consultations may be available with a GP referral for those within Australia.
