Ok, so John Grimaud appears to be the Managing Director of Proactive Sports Management Australia.
Their Transfermarkt page shows they have more players than AP, but again nothing really to suggest they have deep Bundesliga connections.
Then again, this interesting article says:
Agents John Grimaud, Lou Sticca and, increasingly, Richie Hinton are important as they are charged with moving our best and brightest to overseas clubs.
Grimaud has instigated the transfers of local lads Mitch Langerak (Borussia Dortmund), Robbie Kruse (Fortuna Dusseldorf), Josh Kennedy (Nagoya Grampus) and Matthew Spiranovic (Urawa Reds).

From a different article:
[quote]
Vossen set the ball rolling in a blossoming relationship with Australia back in 2011 when he took the advice of agents John Grimaud and Erwin van der Schaft and flew to Adelaide to watch then teenage prodigy Leckie playing for A-League outfit United.
On the balance and from what is accessible online, I don't think there is much online to suggest Libby's immediate departure. And Grimaud's twitter feed reads more like that of an Aussie football fan than that of an agent.
I might well be proven wrong by the facts, but I feel like Grimaud's screenshot was taken out of context by a few (including myself).
