Fair enough. But to be fair, you had not explained that you were number one, with a similar eta, with a jet up your six.
That said, without knowing what else was 'in the picture' I would have thought there might have been 'other' options. 'A few minutes' is the point though, isn't it!
You can bleat on all you like about who is responsible for collision avoidance, but the fact is that in D that collision avoidance is supposed to be provided by traffic information rather than fully blown separation.
That is not correct. Ask your local ATC's [presumably an Australian class D tower] if they are 'required to prevent collisions', and if DTI without a guaranteed 'miss' is meeting their 'legal' requirements.
to deny a clearance and cause delays in order to provide such separation, in fully blown daytime cavok conditions, undermines what D, ICAO

I was no. one but with a jet up my date with a very similar eta. Tower was starting to throw ideas at the jet about how they could make some space
