To build on cropje_jnr's reply, here is a thread about paying tribute. The addition of the word "loving" suggests it was a more personal, emotional tribute (as cropje said, perhaps praising him as a father, rather than for his public achievements).
I do not know what Bindi's actions were, and perhaps other repsondents know if she actually spoke. But one can also pay (loving) tribute to someone with symbolic actions--laying a wreath upon someone's grave or shedding tears, for example.
Yes, Bindi spoke at the memorial service. I don't remember everything she said, but I do remember that she referred to her father as, "my hero". That certainly sounds like a personal, loving tribute to me.
