2005–06 Hong Kong First Division League

Hong Kong First Division League 2005–06 has 8 teams competing in the league. Each team played twice with all other teams. The final champion is Happy Valley, which is their 6th champion. According to the rule, the bottom 2 teams, Hong Kong 08 and South China, should relegate to the Second Division. However, both teams are retained in the division next season by HKFA. Reason for retaining Hong Kong 08 is to give the team better preparation of 2008 Olympics Qualification games. South China was retained because the club promised to expand its next season's budget and sign new quality players. HKFA accepted this and hoped this would improve the competitiveness and attractiveness of the league.
