Are there chances for spouse visa cases in Australia or New Zealand given the budget constraints?

Yes, you can apply for a spouse visa in both Australia and New Zealand even with budget constraints, as long as you meet each country's financial requirements.

- Australia: The Partner Visa requires evidence of a genuine relationship and financial stability, but there is no fixed minimum income. The main applicant fee is AUD 11,710 (subject to change). Showing joint finances and the sponsor's stable income strengthens your case.
- New Zealand: The Partner of a New Zealander Work Visa also focuses on proof of a stable relationship and ability to support yourselves. The main applicant fee is NZD 1,500 (subject to change). Joint finances and shared living arrangements are important.

Both countries expect you to demonstrate you can support yourselves. If your budget is limited, providing clear evidence of joint finances and a detailed budget can help.
