Today, 14 November 2026, is the day Qilin’s displayed countdown points to for publishing information it claims belongs to Calvary Christian College in Mount Louisa. By the later check for this update, the counter on the group’s own listing had passed 7,722 views. Seeing a local school’s name beside a countdown and that much attention is an uncomfortable moment. Behind the logo are children, fa...

An IT consultant can help when your organisation faces a technology decision that needs more investigation than the usual support request.

For a Townsville business, school, charity or community organisation, the useful outcome is a decision you understand ...

I’ve rebuilt and migrated firewalls with a successful cutover involving only a few seconds of downtime. That is a useful outcome for an organisation whose staff depend on its network throughout the day. It is also an outcome that needs context. The interruption achievable on another project depends on the equipment, connection, applications and changes involved. I agree the migration window ar...

Some of the most useful IT consulting happens where several suppliers’ responsibilities meet. The internet provider supplies a connection, the cabling contractor connects the buildings, and the IT team keeps the organisation working. Someone needs to consider how those parts fit together. I’ve assisted organisations with complex NBN connectivity choices and transitions from Fibre to the Node (...

Our family has had a small part in the lead-up to Stable in the City 2026, with Sophie and me dressing as Mary and Joseph, and our three-month-old daughter Madeline joining us for a photoshoot at Sacred Heart Cathedral in Townsville. It was a lovely opportunity to help The Stable NQ promote this year’s event and to be involved together as a family. After years of helping with Stable in other w...
