The duo played together for Vic Metro during the NAB AFL Under-18 Championships over the past two years and have developed into highly-rated players.
Billings' season is over after his Oakleigh Chargers side did not make the TAC Cup finals, but recruiters are well aware of his talent through half-forward and the midfield.
The dynamic 18-year-old marks well above his head for his size, has excellent skills on both feet and is a goalkicker.
Lennon carries some similar traits, and is also a terrific mark-and-lead forward and a piercing kick over any distance.
West Australian prospect Dayle Garlett has been named in the medium forwards category, having failed to be drafted last year with off-field issues the concern for recruiters.
He has shown sparkling form at WAFL level this season for Swan Districts, however, and remains one of the most talented players in the draft pool.
The medium forwards group comprises 27 players between 180cm-189cm.
Of those players, 14 will attend the national combine at Etihad Stadium and 13 will test at state combines around the country.
Jydon Neagle, the son of late Essendon premiership player Merv, has been invited to Victorian state screening. Neagle kicked 10 for NSW/ACT during the under-18 carnival.
