iCal NSW school weeks and terms

Seeking a school term calendar for New South Wales, Australia to subscribe via iOS Calendar app.

The thread iCal NSW school terms from 2012 has outdated links and is now locked, but still ranks highly in Google search results.

As at 2018, the official NSW Education page is now Calendars | Going to a public school, and has a link for an ICS file (https://education.nsw.gov.au/public-schools/going-to-a-public-school/media/docum ents/NSW-public-schools-term-dates-and-h… ).

Unfortunately, this official calendar has four separate entries to cover Eastern vs. Western divisions and student vs. teacher dates. So it's not great for subscription, better to do a selective import.

Calendar-Australia can generate school holidays for a given state and year (e.g. http://www.calendar-australia.com/school-calendars/new-south-wales/2018/0/0/1/1/), but when I subscribe via the iCal link, I just get public not school holidays.

Apart from rolling my own, are there any other suggestions?
