The team qualified for the SP Inter-city Cup in its 1998 season. In their maiden season they lost the second-last. The following season under new coaching staff and new sponsors Toyota they improved significantly coming fourth. In their third season with the smart recruiting of power-house international prop Raymond Karl the Mioks won their first minor premiership and SP Intercity Millennium Cup title in 2000.
Entering the new PNGNRL competition on 2005 they had a scrappy season finishing a lonely second last. In 2006, however they improved just missing out on the finals play off by points difference.
Mioks were runners up in 2009 to Rabaul Gurias losing 24-14 and again in 2018 to Goroka Lahanis losing 10-6. Mioks eventually won the Exon-Mobil Digicel Cup in 2023 again against Goroka Lahanis 26-6.
