any idea how to get australian holidays?

Answer 1

Google Calendar API is returning the correct results, but it is returning them across several pages. You can get the next page with:
https://www.googleapis.com/calendar/v3/calendars/en.australian%23holiday%40group.v.calendar.google.com/events?key=YourApiKey&pageToken=CjASLgojMjAyMTA0MDVfNjBvMzBjaGk2b28zMGMxZzYwbzMwZHI1NmsYkN324_Pw7gIaDwgAEgAYmKz8oN6Y7wIgASIHCAIQzunfEQ==
See more about pagination here: https://developers.google.com/calendar/v3/pagination
The client libraries make it easy to deal with these multi-paged responses.
The page size defaults to 250 events, but this also includes deleted events, which you are not requesting. The first 250 events on this particular calendar have been marked as deleted, so you see an empty page.
See details at: https://developers.google.com/calendar/v3/reference/events/list
maxResults (integer)
Maximum number of events returned on one result page. The number of events in the resulting page may be less than this value, or none at all, even if there are more events matching the query. Incomplete pages can be detected by a non-empty nextPageToken field in the response. By default the value is 250 events. The page size can never be larger than 2500 events. Optional.
I was able to force everything onto a single page using the following, but this really isn't a good answer. If total event count is larger than 2500, you still might end up with an incomplete list:
https://www.googleapis.com/calendar/v3/calendars/en.australian%23holiday%40group.v.calendar.google.com/events?maxResults=2500&key=[YOUR_API_KEY]'

Answer 2

There seems to be an error in that the initial response returns no events however there is a page token This is not how the system is intended to function. I have submitted an issue report
try me
Request;
curl \
'https://www.googleapis.com/calendar/v3/calendars/en.australian%23holiday%40group.v.calendar.google.com/events?key=[YOUR_API_KEY]' \
--header 'Accept: application/json' \
--compressed
Returns
{
"kind": "calendar#events",
"etag": "\"p33kpjmcjvaeuu0g\"",
"summary": "Holidays in Australia",
"updated": "2021-03-06T07:14:02.000Z",

"items": []
}
Where it should return events
If i then add the next pagetoken
