SELECT e.emp_name,
       e.dep_id,
       e.salary,
       e.commission
FROM employees e,
     department d
WHERE e.dep_id = d.dep_id

  AND e.salary BETWEEN 2000 AND 5000;

Sample Output:

 emp_name | dep_id | salary  | commission
----------+--------+---------+------------
 BLAZE    |   3001 | 2750.00 |
(1 row)

Explanation:

This is a SQL query that selects the employee name, department ID, salary, and commission for all employees from the employees and department tables.

The query is using an inner join in the WHERE clause to combine data from the employees and department tables based on their common column dep_id. It then includes the employees who work in the department located in Perth and whose salary is between 2000 and 5000.
