After a bill has been introduced what happens next in the lawmaking process

The member have to debate it and then vote for it

When the bill is accepted through the House of Representatives (lower house), the bill is then passed on to the upper house (Senate House) and further debated upon. If the majority of seats in the Senate House belongs to the Government Party, the bill can be easily passed through.

If the majority of seats belongs to the Opposition, the passing of the bill might get complicated. The debating of passing the bill is pursued and voted upon. If the bill needs amendments, it'll be passed back to the lower house and the entire process is repeated until the bill is passed to both the houses (bicameral legislature)
