If the company has a clear policy on medical benefits, you follow that policy. If there is no such policy, Section 60F of the EA quoted below can be used as a guide. It says "..examination at the expense of the employer...". By, that I think "consultation expenses" mentioned by you could be the one the staff may be entitled to if the company doesn't have a panel doctor.
60F(1) An employee shall, after examination at the expense of the employer:
(a) by a registered medical practitioner duly appointed by the employer; or
(b) if no such medical practitioner is appointed or, if having regard to the nature or circumstances of the illness, the services of the medical practitioner so appointed are not obtainable within a reasonable time or distance, by any other registered medical practitioner or by a medical officer;
be entitled to paid sick leave.
